Lake Der-Chantecoq (French: Lac du Der-Chantecoq) is situated close to the commune of Saint-Dizier in the departments of Marne and Haute-Marne. It is the largest artificial lake in Western Europe, covering 48 km2 (19 sq mi) with 350 million m³ of water. The lake is named after the Der plain, in which it is located, and the submerged village Chantecoq.
The lake is fed by a 12 km long canal that branches off the river Marne in Saint-Dizier. The outflow of the lake is a canal that joins the Marne in Arrigny, 20 km downstream of Saint-Dizier. The lake is located in the communes (clockwise starting from the north) Sainte-Marie-du-Lac-Nuisement, Éclaron-Braucourt-Sainte-Livière, Giffaumont-Champaubert, Arrigny, Larzicourt and Écollemont.
It was created in 1974 to hold the water of the River Marne so that flooding of the Seine at Paris would stop. It is managed by Les Grands Lacs de Seine. Its construction required the destruction of three villages; Chantecoq (Marne), Champaubert-aux-Bois and Nuisement-aux-Bois.
Today, many water sports are popular here, including sailing, water skiing, jet-ski, wind surfing, fishing, rowing etc. as well as walking, rollerblading and cycling around its edges.
